Reverse osmosis membrane

Specifications 1. Ultra low pressure operating pressure

2. Feed TDS less than 2000ppm

3. High salt rejection rate

4. High permeate flow

1.ULP ( Ultra Low Pressure ) series is the latest research and development of environmental protection for surface water and groundwater desalting super low aromatic polyamide composite membrane element, to ultra low operating pressure conditions hit and conventional low-pressure membrane the same high water flux and high desalination rate. The operation pressure of about conventional low voltage composite membrane operation pressure of 2 / 3, desalination rate up to 99.5% and thus reduce the associated pumps, piping, vessels and other investment cost of the equipment and reverse osmosis system operating costs, enhance economic efficiency. 2. ULP series of membrane element is applied to the salinity of about 2000ppm below the surface water, groundwater, water and municipal water, water desalination, mainly used in a variety of sizes of pure water, boiler water supply, food processing and pharmaceutical manufacturing industry and other fields 3. Important information 1-For any recommended design scope,please refer to the latest version of technical manual, design guide, or consult experts proficient in membrane technology.In case the customer fails to follow the operating conditions as specified in this manual, Hangzhou HaiNa environmental protection Technology Co., Ltd. will assumes no liability for all results. 2-The permeate flow listed in the table is the average value. The difference between the lowest permeate flow of single membrane element and nominal flow is not larger than 20%. 3-Before leaving the factory, all wet membrane elements will have been strictly tested, and have been treated for storage with the solution of 1.0% sodium hydrogen sulfite (anantifreeze solution of 10% propanediol will further added in winter), then packed in vacuum, and outer packing is carton. In order to prevent the breeding of micriobes during short-time storage, transportation and system standby, we recommend you to soak the membrane elements with the protective solution (prepared with RO permeate water) containing 1.0% sodium hydrogen sulfite (foodstuff-purpose). 4-Discard RO product water produced during the first one hour after system start-up. 5-During storage time and run time, it is strictly prohibited to add any chemical medicament, which may be harmful to membrane elements. In case of any violation in using this kind of chemical medicament, Hangzhou HaiNa environmental protection Technology Co., Ltd. assumes no liability for all results.  4.
